Does Corningware Contain Lead?

As previously mentioned, brand-new Corningware does not contain lead, but vintage ones might have non-food-safe levels of lead. And by vintage, we mean pre-mid-2000s. Its lead content is mainly due to leading cookware brands during that era predominantly using paint with lead content.

Testing for lead on vintage Corningware products will likely detect around 15,000 - 100,000 PPM lead, but it's mostly on the outer surface that's been painted on. However, such rates of lead are still deemed hazardous to your health.

Years passed and of course, regulations have changed and safer products are being made, so cookware brands have also shifted to safer products.

Blue Cornflower

Based on a test conducted by Lead Safe Mama, Blue Cornflower Corningware cookware tested negative for lead, with the post dating back to 2017. With that, it's safe to assume that new productions of this cookware variant are safe for use in food in the oven or the freezer.

Spice Of Life

Lead Safe Mama also tested a vintage Spice of Life casserole from around 1972-1988, which showed results of 26,500 PPM of lead and 236 PPM of cadmium. For your added information, 90 PPM levels of lead are already considered unsafe for children.

Additionally, Lead Safe Mama also tested a plain white surface of the same Spice of Life casserole which came back negative for lead.

French White

Since French White Corningware is devoid of any paint, it's safe to assume that it's free from lead. While it has been glazed, a majority of glaze paint products are lead-free.

Furthermore, the California Department of Public Health notes that plain white dishes are generally free from lead.

When did Corningware stop using lead?

Corningware says that they stopped using products containing lead around the year 2000. Around and prior to the 1990s, almost all glass and ceramic products included lead in their production, including cookware. However, with the advancement of technology and the invention of safer alternatives, brands have also begun shifting to non-toxic materials.

How do I clean my stained Corningware dishes?

While Corningware is generally made to be stain-resistant, there are certain agents that are just so tough they'd cling to anything. Cleaning stained Corningware is easy, and here's a quick solution you can follow.

  1. Bring 3 cups vinegar, 4 cups water, and 2 tablespoons citric acid to a boil in a big pot.
  2. Place one Corningware dish into the boiling mixture for five minutes. Make sure the water covers the entirety of the dish so it's fully absorbed.
  3. After 5 minutes, check if the stains have come off. If there are still some grimy bits and pieces left, scrub them off with a sponge or a gentle scouring pad.
  4. Repeat the same steps for other Corningware dishes.
  5. Let the dishes dry on a rack or anything similar.

People who have been exposed to lead may find themselves having high blood pressure, headaches, constipation, muscle pain, or fatigue. Those who have had the exposure may also look completely fine, physically, with no signs of having lead poisoning.

If you or know someone who has lead poisoning, you may get a blood test immediately from anywhere near you that does it.

Children are more vulnerable to dangerous diseases once exposed to lead, so it's always best to take professional action as soon as possible.

Furthermore, exposure to highly toxic levels of lead can cause anemia, weakness, and kidney and brain damage.

What to do after lead poisoning

As added care, you can also help decrease the amount of lead present in your body by maintaining a healthy diet after being lead-poisoned. Some of the products you can include in your diet are:

  • Calcium-rich products, such as milk, dairy, tofu, and cereals
  • Green and leafy vegetables
  • Canned fish, such as salmon, tuna, or sardines
  • Lean red meat
  • Iron-rich meals like pasta, bread, and cereal
  • Beans and lentils
  • Oranges, lemons, grapefruit, and other citrus fruits rich in Vitamin C
  • Brocolli

These food products can help your body recover from being deficient in iron and calcium brought on by lead poisoning, so always watch out for your diet afterward, and don't hesitate to seek medical help if you feel something odd with your health.

Since stoneware is made at higher temperatures and so becomes tougher and more durable, it is typically a safer alternative than earthenware or any other material. Glass, especially soda lime glass, borosilicate glass, and glass ceramic, is one of the safest solutions. Lead may be present, but it does not readily or visibly leak out of the surface.
